ECO-WORTHY 2-Pack 12V 30Ah LiFePO4 Battery with BMS Protection 768Wh, 3000+ deep cycles, protection, 1/3 weight of lead-acid, Perfect for Trolling Motor, Fish Finder, Solar System

Lightweight Design: 12V 30Ah LiFePO4 battery is a replacement for lead-acid batteries, with dimensions of 7.2 * 3.3 * 6.9 inches (1/2 of lead-acid batteries) and a weight of 7.05 pounds (1/3 of lead-acid batteries). However, it can be charged over 3000+ times in deep cycling (8 times that of lead-acid batteries) and still maintain 80% capacity thereafter Wide application:ECO-WORTHY 12V lithium battery is a perfect replacement for any 12V deep cycle battery. It is suitable for Fish Finders, backup power, LED lights, Alarm Systems, Emergency Lighting, and more BMS Comprehensive Protection: The lithium battery has a built-in Battery Management System (BMS) that can protect it from overcharging, deep discharge, overload, overheating and short circuit, and low self-discharge rate Capacity Expansion: The batteries support series and parallel connections for larger capacity and higher voltage. For instance, to build a 48V battery bank, you can arrange 4 identical batteries in a 2P4S configuration (two parallel groups connected in series), which is within the recommended limit of no more than 4 units per parallel string Suggestions: Recommended with ECO-WORTHY 12V 5A or 10A Automatic Smart Battery Charger. When LiFePO4 battery is completely protected by BMS, ECO-WORTHY battery charger can activate the battery, charge the battery normally, and restore the battery to normal voltage state
